For properties that are underutilised because of the slope of the landscape, retaining walls can be incredibly useful. Although these walls have multiple applications, their main purpose is to hold back the soil, thus preventing movement of the soil down the slope.
There is a variety of materials that can be used to construct retaining walls. Here are some popular material selections for you to consider.
Concrete blocks are by far one of the most widely used materials for the construction of retaining walls owing to their availability, strength and weight. The raw materials used to create concrete blocks — sand, cement, gravel and water are abundantly available.
The strength and weight of concrete blocks make for sturdy retaining walls, which are imperative for applications that require holding back a lot of soil on sloppy landscapes.
For applications where the strength and weight of concrete blocks do not suffice, natural stone is a great alternative to concrete blocks. Though it may erode gradually over time, natural stone doesn't crack like concrete.
Natural stone retaining walls are also an ideal choice for property owners that desire a natural look for their landscapes. The unique beauty of natural stone means that your retaining walls will stand out from others.
Although timber is usually an inexpensive and sustainable choice for a retaining wall, it's a relatively poor choice due to its shorter lifespan. Although the wood is usually treated to protect it from attacks by wood-loving insects, no wood is immune to decay.
As the wood decomposes over time, so does your retaining wall. This jeopardises the structural soundness of your useful space.
These blocks are a modern alternative to traditional concrete blocks, and their use in landscaping applications is prevalent. They are available in varying levels of opacity and come in a wide variety of colours, styles and designs, including but not limited to plain blocks, frosted blocks and curved blocks.
While glass blocks aren't as strong and durable as their concrete cousins, they are favoured for their superior aesthetic qualities.
When it comes to the construction of retaining walls, there are several types of materials that you can use. Establishing your landscaping needs beforehand is essential to selecting the right retaining wall material. If you need help with choosing the correct material for your retaining walls, you can always discuss your needs with a landscaping contractor near you.
